the molded mouthpiece. This impression should 7 pieces may be used for other purposes other than conform to that part 0! the mouth where the pipe to tobacco uses. For example, such as mouthpieces {or musical instruments, etc. The essence oi the invention is the formation of the mouthpiece, the making of the impression therein which fits exactly the gripping surfaces of the teeth of the individual user and then giving the mouthpiece a properly shaped rod or other metal piece inserted into the opening while the impression is being made. In place of the metal rod a small tube liner may be inserted into the mouthpiece during the impression taking.

What I claim is:

A process of producing an improved mouthpiece tor smokers use by forming a mouthpiece from initially fusible plastic material capable after being formed of receiving an impression in the outer surface thereof, making an impression in the formed mouthpiece with the teeth of the individual user, and then heat hardening the mouthpiece whereby a durable iniusible plastic mouthpiece is obtained.
